One of the most common mistakes in trailer video editing is failing to establish a strong narrative flow. A trailer should not just showcase scenes but tell a compelling story, building anticipation. Another common mistake is poor pacing, too fast or slow, and a need for smooth transitions between scenes. Additionally, neglecting sound design can hinder the emotional impact of the trailer. Incorrect color grading and inconsistent visual effects are frequent errors that detract from a trailer’s overall quality. Avoiding these common mistakes ensures a trailer that captivates and engages viewers from start to finish.
